"Nuclear horseradish." An extremely spicy condiment of Japanese origin, made from the root of the wasabi plant, ranking just below uranium in terms of destructive potential. Allowing any more than twelve molecules of this pungent spice to touch your tongue will cause your head to explode. Well, it will feel like that anyway. When used correctly, good for cleaning out the sinuses and warding away unwelcome guests. Wasabi is available in paste or powder form.

Commonly used in sushi, but also in various other dishes including sashimi, or to flavor udon, soba, ect. Keep away from the eyes. Do not inhale. Do not attempt to feed to pets. If you exceed the recommended dosage (approx 1/4 teaspoon) seek medical help immediately, lest your intestines disintegrate.

Much of the 'wasabi' available in European nations and the Americas is total crap and isn't much spicier than pepper. You'll know it's the real stuff when you start breathing flames and your appendix explodes.

A hot spicy green paste-like sauce used widely in japanese cuisine, especially with sushi. Has a taste reminiscent of horseradish or mustard, but much stronger. Real wasabi is made from grinding the stem of the Japanese horseradish plant (wasabia japonica) and mixing it with water. However the most common wasabi is fake wasabi, made from European horseradish, mustard and green food colouring.

A condiment, Japanese in origin, that's popular in the United States. Once ingested, it's pure hell for all of five seconds.

Right after you take a good hit of wasabi, your nose will burn as if you just belched after gulping down a mustard gas soda pop, your eyes will feel like they got sprayed with ammonia, you will become unable to breathe because you don't want to dessicate your lungs into massive pulmonary scar tissue, and this nightmare of physical torture will compound itself on a cosmic scale until you are about to crumple into tearful, humiliating, submissive defeat for foolishly defying the terrible power of the wasabi gods, and then it's overwith. Then you're ready for some more.
